the formula is pi times radius squared times height
- 00:27
The question gives us the radius is 8 and the height
- 00:30
as 12. Plug those numbers into the formula as pie times radius 8 squared
- 00:35
which is
- 00:36
64 times the height which is 12 so 64 times 12 is 768
- 00:42
and don't forget the times pi in there.
